Purpose
To compute the following norms One Norm , I Norm ( max absolute row sum) , Frobenius Norm, Maximum Modulus

> library(Matrix)
> x <- Matrix(10 + 1:16, 4, 4)

One Norm ( Maximum absolute column sum)

> norm(x, "1")
[1] 98

Infinity Norm (Maximum absolute row sum)

> norm(x, "I")
[1] 80

Frobenius Norm

> norm(x, "F")
[1] 76.2627

M Norm - Maximum Modulus of all elements

> norm(x, "M")
[1] 26
